I had a struts application. I made the following changes to the application
1. Added loggers to the application.
2. Separated the functions of creating database connection in separate class and made DAO to extend this new class.
3. One more class added.
4. Created a utility class having static methods.
5. Deployed the new one with a different name at the same place where the original one was deployed.
But after doing so, my application became slow than the original one and the time difference is quite significant.
Could anyone please tell me why this is happening?
Think before you speak as you might hurt or break someone's heart.
Probably not without more information. Have you tried doing the same installation without your changes? Removing some of your changes to see if they make a difference? Profiling the application to determine where the bottlenecks are?
